Held since September 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 53 m² it sits well below the postcode median (89 m² across 18 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 72% of similar EPCs). Across 2003–2007, sale prices on this property compounded at 7.5% per year. Today's modelled estimate of £293,000 is 47.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£348/sq ft) was about 62.3% above the typical sold price in the postcode.
